There are any number of possible threats to life and limb out there...all the time. There always have been. The only one I know of that is being used presently as an excuse for invading other countries in order to steal their oil and achieve world domination is "terrorism".

Ha. Ha. The real terrorists are the ones who announced and are prosecuting the War On Terrorism, and using it to build their dictatorship. Osama was just one of their hirelings, and so was Saddam. When a hireling is no longer useful, you "lay him off" (to put it delicately). Remember when Noriega got laid off? Same basic scenario, different time and place.

When they feel that it is necessary to have another "terrorist" incident occur stateside in order to get continued public support, they will arrange it.
